[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-4 The multi-aperture suction nozzle array device shown includes an array disk 1 and a plurality of suction nozzles 2 located at the bottom of the array disk 1. A negative pressure cover 3 is installed on the top of the array disk 1. A negative pressure chamber 4 communicating with the suction nozzles 2 is formed inside the negative pressure cover 3. A plurality of solenoid valves 5 connected to the top of the suction nozzles 2 are installed inside the negative pressure chamber 4.

[0022] The suction nozzle 2 includes a cap 6 installed at the bottom of the array disk 1. A suction nozzle tube 7 that can be raised and lowered is inserted inside the cap 6. A limiting member that limits the movement of the suction nozzle tube 7 passes through the outside of the lower cap 6. A detachable suction nozzle head 8 is installed at the bottom end of the suction nozzle tube 7.

[0023] The negative pressure cover 3 is connected to a negative pressure pipe 9 at the top. Several through holes 10 are passed through the array disk 1. The solenoid valve 5 is installed inside the through hole 10. The negative pressure chamber 4 is connected to the suction nozzle 2 through the solenoid valve 5.

[0024] Based on the above, during use, the negative pressure tube 9 is connected to an external negative pressure device. When the negative pressure device is working, a negative pressure is formed inside the negative pressure chamber 4. The negative pressure chamber 4 is connected to the suction nozzle 2 through a solenoid valve 5. Each suction nozzle 2 is connected to an independent solenoid valve 5 at its top. By controlling the opening and closing of the solenoid valve 5, a specific suction nozzle 2 can be selectively activated, realizing independent control of multiple suction nozzles 2, so that a negative pressure is generated at the bottom of the suction nozzle 2 to adsorb the required parts.

[0025] Furthermore, the suction tube 7 in the suction nozzle 2 can be raised and lowered. When adsorbing parts, the suction nozzle 2 can be lowered by one section, and the suction tube 7 can be retracted upward by a certain distance, which can better adsorb the parts. The suction head 8 at the bottom of the suction tube 7 can be detached. During use, the suction head 8 with different aperture can be replaced according to the specifications of the parts to suit the adsorption of different parts.

[0026] The top of the cap 6 has a connecting hole 11 located directly below the through hole 10. The bottom of the connecting hole 11 has a negative pressure hole 12 that penetrates the cap 6. The inner diameter of the negative pressure hole 12 is larger than the inner diameter of the connecting hole 11. The suction tube 7 is inserted into the inside of the negative pressure hole 12. A spring 13 is installed at the bottom of the suction tube 7. The top of the spring 13 is connected to the edge of the connecting hole 11.

[0027] Furthermore, during installation, the array disk 1 is installed at the lifting component of the SMT equipment. During operation, the lifting component drives the array disk 1 to move up and down. When the array disk 1 moves down, it will drive the nozzle 2 to move down, so that the nozzle head 8 at the bottom of the nozzle tube 7 acts on the component. The nozzle tube 7 will be compressed by force, so that it overcomes the effect of the spring 13 and retracts into the negative pressure hole 12, making it easier for the nozzle head 8 to pick up the component.

[0028] Furthermore, when adsorbing the element, the suction nozzle 7 retracts under external force, and the spring 13 buffers the pressure to avoid damage to the element.

[0029] The negative pressure hole 12 inside the cap 6 is connected to the inside of the suction tube 7, and the negative pressure hole 12 is connected to the inside of the negative pressure chamber 4 at the top of the array disk 1 through the connecting hole 11 and the solenoid valve 5.

[0030] The suction tube 7 is fitted with a path tube 14. The top end of the path tube 14 is fixed to the bottom of the screw cap 6. The bottom end of the path tube 14 has an upwardly extending path groove 15. The path groove 15 has a limiting block 16 fixed to the outer wall of the suction tube 7.

[0031] The limiting member includes a screw 17 that penetrates the cap 6, with the inner end of the screw 17 extending into the interior of the negative pressure hole 12. A rotating ball bearing 18 is installed at the end of the screw 17 located inside the negative pressure hole 12.

[0032] A recessed limiting groove 19 is provided on the outer wall of the suction tube 7 located inside the negative pressure hole 12. The limiting groove 19 extends along the axis of the suction tube 7, and the ball 18 at the end of the screw 17 fits inside the limiting groove 19.

[0033] Based on the above, the suction tube 7 is also inserted into the interior of the path tube 14. The suction tube 7 is detachable inside the path tube 14 and the cap 6. During installation, the limiting block 16 on the outer wall of the suction tube 7 is aligned with the path groove 15 on the path tube 14. The suction tube 7 is moved upward to insert it into the interior of the path tube 14 and the negative pressure hole 12 until the top of the suction tube 7 contacts the spring 13. At this time, the screw 17 is inserted from the outside of the cap 6 so that the ball 18 at the end of the screw 17 is embedded in the limiting groove 19, thus limiting the suction tube 7 in the negative pressure hole 12.

[0034] Furthermore, when the suction tube 7 is inserted into the negative pressure hole 12, as the suction tube 7 moves up and down, the ball bearing 18 at the end of the screw 17 rotates in the limiting groove 19, limiting the range and angle of the movement of the screw 17, ensuring the stability of the movement path of the suction head 8, and facilitating the adsorption of parts.

[0035] The suction head 8 includes a sleeve 20 fitted on the outer wall of the bottom end of the suction tube 7. The inner wall of the sleeve 20 and the outer wall of the bottom end of the suction tube 7 are provided with matching threads. A funnel-shaped suction tube 21 is provided at the bottom end of the sleeve 20, and a sealing ring 22 is provided at the top end of the sleeve 20.

[0036] Based on the above, the suction head 8 is composed of a detachable sleeve 20 and a suction tube 21. Depending on the specifications of the adsorption parts, the suction head 8 can be replaced with suction tubes 21 of different specifications. The sleeve 20 is installed at the bottom of the suction tube 7 through threads, and the sealing tube contacts the top of the sleeve 20 to improve the sealing of the suction head 8 and ensure the effect of negative pressure adsorption.

[0037] Furthermore, the detachable nozzle head 8 design allows for quick replacement of different sizes of suction tubes 21 without replacing the entire nozzle 2, making it suitable for adsorption needs of various sizes of components in the semiconductor and SMT fields, reducing changeover time. The array-type nozzle 2 design supports simultaneous adsorption of multiple components, and combined with the flexible control of the solenoid valve 5, it significantly improves the working efficiency of the pick-and-place machine.

[0038] The independent solenoid valve 5 controls the negative pressure chamber 4 to achieve precise opening and closing of the nozzle 2 and avoid negative pressure leakage; the limit groove 19 and the ball bearing 18 structure ensure the linear movement of the nozzle tube 7 and improve the placement accuracy.

[0039] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
